Polycyclic musks

Class of synthetic fragrances

Polycyclic musks are synthetic fragrances used e.g. in cosmetics, personal care products, household and laundry cleaners, papers and textiles.
Following use, they enter the environment through waste waters and sewage sludge.

Their degradation is slow. They are lipophilic and have a high potential for bioaccumulation.

Some polycylic musks are highly toxic to aquatic organisms. For some compounds photoxicity has been demonstrated, others are neurotoxic in animal experiments and act as endocrine disruptors. Moreover, some musk compounds are suspected to be carcinogenic.
